With little momentum from local news, traders were influenced by a sell-off in US stocks triggered by a stronger US dollar and discouraging signs of a subdued US economic recovery.

Shaw Stockbroking senior dealer Jamie Spiteri said trade was stable amid weaker volumes on Friday.

"The market's predictably easier, but it's remained relatively stable at these lower levels," he said.

"The trading range for the day has only been about 10 or 15 points, so things have remained relatively steady despite the fact that share prices are on the lower side.

"Some of the falls have been across areas which have been weaker over the week, like the banking sector, and we're seeing some profit taking in some of the resources as well."
